Systems and methods for controlling HDA system capabilities

A method implemented by a High Definition Audio (HDA) codec, wherein the HDA codec is for use with an HDA amplification system that includes a connector configured to accept an optional component, the method comprising:

• (a) determining whether the optional component is connected to the connector;
• (b) enabling a baseline subset of a set of audio processing features and disabling one or more audio processing features outside the baseline subset, when the optional component is not connected to the connector;
• and
• (c) enabling an alternative subset of the set of audio processing features that is different from the baseline subset, when the optional component is connected to the connector, wherein the alternative subset includes at least one of the audio processing features that is disabled when the baseline subset is enabled;
• wherein the at least one of the audio processing features that is outside the baseline subset, but is within the alternative subset, cannot be enabled unless the optional component is connected to the connector.

A High Definition Audio (HDA) codec for use with an HDA amplification system that includes a connector configured to accept an optional component, the HDA codec comprising:

• a processor configured to
• determine a set of authorized audio processing features that does not include every audio processing feature which the HDA amplification system is capable of providing;
• and
• determine a set of available audio processing features based on whether the optional component is connected to the HDA amplification system;
• wherein said processor is configured to configure the HDA amplification system to provide audio processing features that are included in both the set of authorized audio processing features and the set of available audio processing features.

• determining a set of available audio processing features based whether the optional component is connected to the HDA amplification system;
• and
• configuring the HDA amplification system to provide audio processing features that are included in both the set of authorized audio processing features and the set of available audio processing features.

A High Definition Audio (HDA) codec for use with an HDA amplification system that is configured to accept an optional plug-in, the HDA codec comprising:

• a processor capable of providing a set of audio processing features;
• wherein said processor is configured to determine whether the system includes the optional plug-in;
• wherein said processor is configured to enable a baseline subset of the set of audio processing features, and disable one or more audio processing features outside the baseline subset, when said processor determines that the system does not include the optional plug-in;
• wherein said processor is configured to enable an alternative subset of the set of audio processing features that is different from the baseline subset and that includes at least one of the audio processing features included in the baseline subset, when said processor determines that the system includes the optional plug-in;
• and
• wherein the at least one of the audio processing features included in the alternative subset, but not included in the baseline subset, cannot be enabled unless the system includes the optional plug-in.

A method implemented by a codec, wherein the codec is for use with an amplification system that is configured to accept an optional plug-in, the method comprising:

• determining whether the optional plug-in is installed or otherwise accepted;
• enabling a baseline subset of a set of audio processing features, and disabling one or more audio processing features outside the baseline subset, when the optional plug-in is not installed or otherwise accepted;
• and
• enabling an alternative subset of the set of audio processing features that is different from the baseline subset and that includes at least one of the audio processing features included in the baseline subset, when the optional plug-in is installed or otherwise accepted;
• wherein the at least one of the audio processing features included in the alternative subset, but not included in the baseline subset, cannot be enabled unless the optional plug-in is installed or otherwise accepted.
